Technical Field

[0001] The utility model relates to the technical field of filling machinery, in particular to a position-limiting anti-rotation locking auxiliary structure. Background Art

[0002] With the expansion of beer production and the improvement of consumers' requirements for product quality, higher requirements are placed on the operating stability of beer machines. During the operation of the beer machine, frequent rotation and connection operations of the connecting pipe part are inevitable. In order to improve work efficiency and reduce the difficulty of operation, it is particularly important to design an auxiliary structure for the connecting pipe part that is easy to rotate. This structure can simplify the connecting pipe process and enable operators to complete the connecting pipe task more quickly and accurately. The beer machine needs to maintain stable performance during operation to ensure the quality and taste of the beer. The stability of the connecting pipe part directly affects the operating status of the entire beer machine.

[0003] In the prior art, the connecting pipe part of the beer machine often has the following problems: when the knob is rotated to the last few turns, the user needs to use more force to turn the knob, and when the user needs to completely close the knob, it often requires more force; and when the connecting pipe part of the beer machine is installed, since the inner shaft is installed first and the outer shaft is installed later, it is easy for the inner shaft to rotate with the outer shaft, resulting in a situation where it cannot be fixed. Utility Model Content

[0004] (I) Technical problems to be solved: With regard to the prior art, when the knob is rotated to the last few turns, the user needs to use greater force to turn the knob, and when the user needs to completely close the knob, even greater force is often required; also, when the connecting pipe part of the beer machine is installed, the inner shaft is installed first and then the outer shaft, which easily causes the inner shaft to rotate with the outer shaft, resulting in the insufficiency that it cannot be fixed. The utility model provides a position-limiting anti-rotation locking auxiliary structure, which adds an auxiliary structure to the connecting pipe part of the existing beer machine, so that the knob of the connecting pipe part of the beer machine is easy to turn and the inner shaft is easy to fix.

[0005] (II) Technical solution: To achieve the above-mentioned purpose, the utility model provides the following technical solution: a position-limiting anti-rotation locking auxiliary structure, which includes a rotating shell, which is used together with an external knob, and the outer ring surface of the rotating shell is designed with array-distributed convex patterns, which are in the shape of long strips and extend from one end of the rotating shell to the other end; the external knob is an annular structure, and the annular inner ring of the external knob is designed with a hollow structure that matches the convex pattern; if the external knob is in a mutually coordinated state with the convex pattern on the annular outer surface of the rotating shell through the hollow structure on its annular inner ring, then when the external knob is rotated, the rotating shell can be driven to rotate together.

[0006] Preferably, the structure further includes a positioning inner core, which is used in combination with the fixed handle. An array of card slots is designed at the intersection of the surface of the positioning inner core facing the outside of the machine and its circumferential outer surface, and the number of the card slots is greater than or equal to two. A protruding structure adapted to the card slot is designed at one end of the fixed handle. When the card slot cooperates with the protruding structure of the fixed handle, the positioning inner core loses its rotational freedom.

[0007] Preferably, the other end of the fixed handle is designed as a bent structure to form a grip, and the grip and the fixed handle form a right-angle structure.

[0008] Preferably, a groove structure is designed on the inner surface of the card slot, and the number of the groove structures is greater than or equal to one.

[0009] Preferably, both the positioning inner core and the rotating outer shell are made of waterproof and corrosion-resistant metal materials.

[0010] Preferably, the height of the convex stripes gradually increases from the outside to the inside, remains at the highest point, and continues to extend evenly until the end, forming a smooth surface.

[0011] Preferably, an array of tooth structures is designed on the circumferential outer surface of the external knob, and the number of the tooth structures is greater than two.

[0012] Preferably, the rear surface of the external knob is hollowed out, and the external knob is made of plastic material.

[0013] Preferably, an array of reinforcing rib structures is designed on the rear surface of the external knob.

[0014] (III) Beneficial effects: Compared with the prior art, the present utility model provides a limiting and anti-rotation locking auxiliary structure, which has the following beneficial effects:

[0015] 1. The position-limiting anti-rotation locking auxiliary structure is designed with a rotating shell, and the outer ring surface of the rotating shell is designed with array-distributed convex patterns, the convex patterns are in the shape of long strips, and the cross-section is in the shape of an arc, and the convex patterns extend from one end of the rotating shell to the other end; the rotating shell is used in conjunction with the external knob, and the external knob is an annular structure, and the inner ring of the annular ring of the external knob is designed with a hollow structure that matches the convex patterns. When the external knob is nested on the outside of the rotating shell, and the hollow structure matches the convex patterns, the user can rotate the rotating shell together by twisting the external knob. Compared with the prior art, the torque can be flexibly increased without changing the size of the conventional beer machine pipe part, and the beer machine pipe part can be easily rotated by using the lever principle. The method of designing convex patterns on the rotating shell and using it together with an external knob has the advantages over simply enlarging the knob in the prior art. By putting an external component on the existing knob, the original design or structure can be kept basically unchanged, while increasing the convenience of use. This method does not require large-scale modification or replacement of the original equipment, and is particularly suitable for scenarios where it is difficult to replace the entire knob due to space limitations or cost considerations. Directly replacing a larger knob may involve higher costs, including material costs, manufacturing costs, and possible installation and debugging costs. In contrast, putting on an external component may only require the purchase of an additional part, and the installation process is relatively simple, thereby saving costs. If the original knob design or size needs to be restored in the future, the method of putting on the external component can be more easily implemented, and the external component can be restored to the original state by simply removing it, without causing permanent changes to the device.

[0016] 2. The position-limiting anti-rotation locking auxiliary structure is designed with a positioning core, and the intersection of the side of the positioning core facing the outside of the machine and the circumferential outer surface is designed with an array of slots, and the number of the slots is greater than or equal to two; one end of the fixed handle used in conjunction with the positioning core is designed with a protruding structure that matches the slot. The two structures cooperate with each other to enable the fixed handle to engage with the positioning core. When the positioning core is installed inside the pipe connection part of the beer machine, and its external components need to be connected to the positioning core using threads, the engaging structure of the fixed handle and the positioning core is used to ensure that the positioning core remains fixed inside the pipe connection part of the beer machine and does not move with the rotation of the external components, thereby improving the installation efficiency of the pipe connection part of the beer machine and optimizing the difficulty of operation during the quality inspection of the pipe connection part.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Such as Figure 1 And Figures 4 - 5As shown, the position-limiting anti-rotation locking auxiliary structure comprises a rotating shell 2, the rotating shell 2 is used together with an external knob 3, the outer ring surface of the rotating shell 2 is designed with an array of convex patterns 201, the convex patterns 201 are in the shape of long strips, the convex patterns 201 extend from one end of the rotating shell 2 to the other end so that the external knob 3 can be embedded in the rotating shell 2 by sliding; the external knob 3 is an annular structure, and the annular inner ring of the external knob 3 is designed with a hollow structure (301) adapted to the convex patterns 201; if the external knob 3 is in a mutually matched state with the convex patterns 201 on the annular outer surface of the rotating shell 2 through the hollow structure (301) on its annular inner ring, when the external knob 3 is rotated, the rotating shell 2 can be driven to rotate together. Compared with the prior art, the torque can be flexibly increased without changing the size of the conventional beer machine pipe part, and the beer machine pipe part can be easily rotated by using the lever principle. The method of designing a convex pattern 201 on the rotating housing 2 and using it together with the external knob 3 has the advantages over the simple enlargement of the knob in the prior art in that: by putting an external component on the existing knob, the original design or structure can be kept basically unchanged, while increasing the convenience of use. This method does not require large-scale modification or replacement of the original equipment, and is particularly suitable for scenarios where it is difficult to replace the entire knob due to space limitations or cost considerations; directly replacing a larger knob may involve higher costs, including material costs, manufacturing costs, and possible installation and debugging costs. In contrast, putting on an external component may only require the purchase of an additional component, and the installation process is relatively simple, thereby saving costs; if the original knob design or size needs to be restored in the future, the method of putting on the external component can be more easily implemented, and the device can be restored to its original state by simply removing the external component, without causing permanent changes to the device.

[0025] like Figures 1 - 3 As shown, the structure also includes a positioning core 1, which is used together with a fixed handle 4. The intersection of the side of the positioning core 1 facing the outside of the machine and the circumferential outer surface is designed with an array of slots 101, and the number of the slots 101 is greater than or equal to two; one end of the fixed handle 4 is designed with a protruding structure 401 adapted to the slot 101; when the slot 101 and the protruding structure 401 of the fixed handle 4 cooperate with each other, the positioning core 1 loses the degree of freedom of rotation. These two structures cooperate with each other to make the fixed handle 4 and the positioning core 1 engage. When the positioning core 1 is installed inside the pipe part of the beer machine, and its external components need to be connected to the positioning core 1 by threads, the engagement structure of the fixed handle 4 and the positioning core 1 is used to ensure that the positioning core 1 remains fixed inside the pipe part of the beer machine, and does not move with the rotation of the external components, thereby improving the installation efficiency of the pipe part of the beer machine and optimizing the difficulty of operation during the quality inspection of the pipe part.

[0026] As Figure 3 shown, the other end of the fixed handle 4 is designed as a bent structure to form a grip 402. The grip 402 and the fixed handle 4 form a right-angle structure, enabling the operator to more conveniently hold the fixed handle 4 when using the fixed handle 4 for fixation.

[0027] As Figure 2 shown, the inner surface of the card slot 101 is designed with a groove structure 102. The number of the groove structures 102 is greater than or equal to one, which realizes double limit for the positioning inner core 1.

[0028] As Figure 1 shown, both the positioning inner core 1 and the rotating housing 2 are made of waterproof and corrosion-resistant metal materials to improve the service life of this structure.

[0029] As Figure 1 shown, the height of the convex stripes 201 gradually increases from the outside to the inside. After reaching the highest point, it maintains the height and continues to extend evenly until the end, forming a smooth surface to facilitate sliding during sleeving.

[0030] As Figure 4 shown, the circumferential outer ring surface of the external knob 3 is designed with tooth structures 302 distributed in an array. The number of the tooth structures 302 is greater than two. The concave-convex structure formed by the tooth structures 302 increases the friction force on the hand when the external knob 3 is used, and the force effect is better.

[0031] As Figure 5 shown, the rear surface of the external knob 3 is hollowed out. The external knob 3 is made of plastic material, which not only reduces the weight of the external knob 3 to make it more portable, but also realizes the waterproof function by using plastic material.

[0032] As Figure 5 shown, the rear surface of the external knob 3 is designed with rib structures 303 distributed in an array to make this structure more stable.

[0033] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in combination with the embodiments.
